DUMP-CAR-DOOR CONTROL.

This invention relates to dump cars and is particularly designed to facilitate manual control of a dump car door, for instance, a door mounted to swing outwardly upon a horizontal hinge, and thereby limit the degree of opening of the door and prevent too sudden discharge of the lading or graduate the outflow of lading such as ballast, when it is desired to distribute it along the railroad; such manual control being also useful in case it be desired to force the door in the closing direction to admit the securing means into locking position or to counteract internal pressure against the door while withdrawing the securing means from locked position.

The invention proceeds upon the principle of equipping a swinging door with means through which a bar or handle of sufficient length to develop a substantial leverage, may be applied to the door, with such rigidity in the direction of closing movement as to adapt the door, through the bar, to be forcibly pressed or resisted in said direction, and held at a desired degree of opening, or in fully closed position, while a latch or securing device is being manipulated; the means for so rigidly relating the bar being preferably in the form of a socket that is permanently mounted on the door and presented in a position relatively thereto which will facilitate insertion of the leverage bar by an operative standing at the outside of the car.

In the accompanying drawing, in which the preferred embodiment of the invention is shown by way of illustration- Figure 1 is a side elevation of an outwardly swinging side-discharge door, together with portions of a dump car immediately surrounding it, and in which the several features of the present invention have been embodied.

Figure 2 is a section on the line 2 2 of Figure 1;

Figures 3 and 4 are, respectively, a front elevation and side elevation of the socket detached; and

Figures 5 and 6 are views corresponding substantially to Figure 2, but showing the door at diflerent degrees of opening, to wit: in full open position which permits an unrestricted discharge over the hopper bottom of the car, and a restricted open position in which but a small volume of outflow will be permitted, and such outflow will be directed immediately downward.

1 represents a door mounted to swing outwardly on overhead hinges 2, in permitting lateral discharge of lading from a railway dump car, the immediately concerned portions of which are represented at 3, d repr sents a latch pivoted at 5 upon the door 1, and adapted to be moved by handle 6 into and out of a keeper '2' mounted on a fixed end of the car, for instance, upon the lower margin of the inclined bottom wall 8 against the lower margin of which the door seats in effecting its closure. Frequently, in attempting to manipulate doors of this kind, or doors subjected to similar influences in use, it is difficult to force the door closely enough to its seat to enable the latch i to enter the keeper 7 or a corresponding looking effect to be attained in whatever securing device may be used; and in such doors, in the absence of means for exerting considerable power upon the securing device, it is always difficult to withdraw the securing device owing to the pressure of lading against the inner faceof the door. Also in doors of this kind, when left unrestrained, there will be a sudden outflow, in full volume, of lading which. is usually in subdivided form which causes the material to reach a point of deposit considerably beyond that desired, particularly when the car is being used to distribute broken stone or ballast.

The present invention remedies the dii'l'e culty above stated by mounting upon the door 1, preferably near its lower margin or most remote point from the hinges 2, and at least at such distance from the hinges as ivill afford an advantageous distribution of force, a lever-receiving member 9, preferably in the form of a socket 9, an attaching base 9*, and such design of strengthening webs 9 as may be found desirable in sustaining the socket 9 transversely; and this lever-applying means is permanently secured to the door, as, for instance, by rivets 10. The lever-applying device may be mounted with advantage in the angle of the lower L-shaped reinforce cleat 11, as shown more clearly in Figures 2, and receive further sustention from the latter; to which end, the attaching base 9 and strengthening web 9 are related to each other with the same angularity as are the members of the said cleat. The presentation of the .socket 9 is in the direction which will render convenient the insertion thereinto of a shaft or bar, such as 12, from a position conveniently assumed by an operative, and at the same time give to the lever which thus becomes rigidly related to the swinging doorfa presentation which will develop forcible closing movement under the manipulation which the operative can conveniently perform, for instance, by pressing downwardly on the lever with the hands, or otherwise imposing upon it suiticient weight to force the door inward and permit easy withdrawal of the latch 4 through the medium of its handle 6, it the door is to be released, or holding the door at any desired degree of opening, in opposition to the pressure of outflow-mg material, tor instance, when ballast or other material is bein distributed along the track by releasing it in a restricted stream as the .car moves along and the operative walks alongside, bearing down on the holding lever; or pressing it firmly to its seat in case the door is being closed and the latch is to be moved into locking position.

A door equipped with manual controlling means of the kind described, may even be manipulated to good purpose, as a means of jarring the discharge hopper in case the material becomes impacted around the hop per opening and does not begin to .move when the door is released.

An important advantage arising from the particular embodiment of the present invention selected for illustration, to which, however, the invention is not to be exclusively limited, is that by continuing pressure on the lever 12, the opening of the door 1 may be controlled or resisted, or restricted in the degree of its opening until the operative is enabled to remove himself from the path of discharge.

I claim:

1. A door controlling attachment for dump cars, comprising a lever applying means adapted to be mounted upon the door and constructed to hold a lever in angularly rigid controlling relation to the door.

2. A door controlling attachment for dump cars, comprising a lever applying means adapted to receive a lever and hold it in a-ngi ila-rly rigid relation, and means for attaching said lever applying means to a door to be controlled.

3. A door controlling attachment for dump cars, comprising a lever receiving socket, and means for mounting said socket upon a door to be controlled.

i. A door controlling attachment comprising a socket, and a base plate integral with said socket and constructed to be attached to a door to be controlled.

5. A door controlling attachment comprising a socket, and :an angular ibase upon which said socket is mounted and which is constructed for attachment .to a door to be controlled.

6. A cogtrolling attachment for .doors, comprising an attachment plate and strengthening web angularly related to said plate, and a socket integral with said plate and web.

7. In combination, a swinging loor, a socket rigidly related to said door at a point remote from its swinging axis and adapted to receive and hold, in angularly rigid relation to the door, a lever for swinging the door.

8. In combination with a door, a socket for receiving a door controlling lever, an attaching plate mounting said socket upon the door, and a stiffening web projecting at a substantial angle from said attaching plate.

9. In combination with a door having an angular cleat, a socket for a door cont-rolling lever, and a .base and strengthening web integral with said socket, angu larly related one to the other .and fitting the angle of the cleat.
